S-III: incorrect sequence during phase switch

Hva betyr F4017 ?

This fault indicates an incorrect sequence of communication phases during a switch, specifically related to phase S-III operation on the IndraDrive MPx02. This can disrupt the synchronous operation of the drive.

• Master communication device sending an incorrect phase sequence or timing.
• Incorrect configuration of communication parameters in the IndraDrive MPx02 (e.g., S-0-0010, S-0-0011).
• Disturbances or interference on the communication bus during phase switching.
• Software or firmware issues in either the master controller or the IndraDrive MPx02.

1. 1

   Verify the communication master's configuration for phase switching and sequence, ensuring it aligns with the IndraDrive MPx02 requirements.

2. 2

   Check communication parameters in the IndraDrive MPx02, such as S-0-0010 (Master communication cycle time) and S-0-0011 (Drive communication cycle time), for correct settings.

3. 3

   Inspect the communication bus cabling (e.g., SERCOS, EtherCAT) for proper termination, shielding, and absence of damage.

4. 4

   Monitor the communication signals for integrity and noise using appropriate diagnostic tools, if available.

5. 5

   Update the firmware of the IndraDrive MPx02 to the latest version, if applicable, to address potential known issues.
